the style being bent upwards the visitor first comes into contact with the stigmatic 

 papillae. Later on the style straightens out, so that it applies itself to the under-side 

 of the corolla. On creeping further into the flower, the insect is covered with fresh 

 pollen, which it can no longer transfer to the stigma of the same flower. Morren, 

 nevertheless, considered the flower mechanism self-pollinating, because he thought 

 that the pollen falling on the corolla could reach the stigma.

Blue Lepidopterid flowers. Numerous florets are aggregated into a rounded 

 head. They secrete nectar from the fleshy base of the ovary and store it in the 

 corolla-tube, this being, however, so narrow that the nectar is only accessible to the 

 thin proboscis of Lepidoptera. Each corolla-tube is divided into five linear lobes, 

 two shorter upper and three longer lower ones. Between these two shorter upper 

 and two longer lower stamens are placed. When these diverge and are widely
